Standard Features

Durably Constructed to Withstand Wear and Tear Resulting from Repetitive Use

With durable plastic housing, a protective cap that safeguards the sensor and an automatic
shutdown feature to preserve battery life, the Starter pen meters can endure consistent use
in rugged environments.

Waterproof Housing Protects the Meters in their Working Environment

Equipped with a wrist strap that helps to prevent unintentional dropping, Starter pen
meters are constructed with an IP67 waterproof design that can prevent
water damage when accidentally dropped into liquid


After more than a century of perfecting the art of measurement through our durable weighing products, OHAUS precision is now available in a line of pen meters that provide accurate measurement of pH, oxidation-reduction potential (ORP), conductivity, salinity, and total dissolved solids (TDS).
